Mech infantry dismount under fire

Drone footage from Ukraine’s 79th Brigade showing mechanized infantry dismounting while under observation and immediately taking fire. The Russian soldiers dismount their BMPs with almost no cover and minimal concealment and proceed to file along a road like lemmings. Ordnance explodes in their midst, either from a drone-dropped munition or a mortar round. Drones begin to pick off the dismounts as they huddle near their vehicles or scramble for refuge in the brush. Using conventional wisdom, mechanized infantry can dismount in a position offering cover and concealment and then proceed to their objective on foot, with vehicles, IDF, and other assets providing cover as they advance. Or the IFVs can roll up on the objective and drop the dismounts there, though the vehicles also require that supporting assets suppress enemy fires as they advance. I offer that this technique is not doctrinally sound.
